我对maven和servlets还不熟悉，但我完全不知所措。它拒绝在每一个转折点上工作，并且出于某种原因，它说“无需编译-所有类都是最新的”，尽管我已经更改了所有需要更改的内容

这是我的servlet：

@WebServlet("/HelloWorld")
public class HelloWorldServlet extends HttpServlet {

@Override
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException {
    response.setContentType("text/html");
    response.setCharacterEncoding("UTF-8");

    String hold = request.getParameter("text");

    try(PrintWriter out = response.getWriter()) {
        out.println("<!DOCTYPE html>");
        out.println("<html>");
        out.println("<body>");
        out.println("<p>"+hold+"</p>");
        out.println("</body>");
        out.println("</html>");
    }
}

您在哪里找到了java文件

src/main/java

+package？您还可以包括maven命令的输出吗？运行

mvn clean-package-cargo:deploy

。这将删除您的目标文件夹并重新编译所有内容。Clean包可以工作，但似乎每次我都必须这样做？我也有同样的问题，我在

src/main/java/

中有源代码，但只有使用Clean包才能编译。
